| description | It is an objective to provide a patch material having both excellent adhesive property and moisture permeability. The present invention is related to a patch material which comprises a backing material having a water-vapor permeability of 3,000 g/m 2 ·day or more and an adhesive layer having a water-vapor permeability of 5,000 g/m 2 ·day or more, wherein the adhesive layer comprises a polyurethane adhesive obtained by reacting (1) an active hydrogen compound having a number-average molecular weight of 5,000 or more and an average number of functional groups of 2 or more, and having a polyoxyalkylene structure, (2) an active hydrogen compound having a number-average molecular weight of 1,500-5,000 and an average number of functional groups of 1, and having polyoxyalkylene structure, and (3) an organic polyisocyanate, wherein an average number of functional groups of all active hydrogen compounds used for obtaining the adhesive is 2-2.6, and the content of ethylene oxide units of all active hydrogen compounds in the adhesive is 3-8% by weight. |
